4 Claims. (01. es-'3 H and the; lower portionsof the bolts pass freely through holes l2 to permit of free sliding move- This invention relates to laundry presses as used for the pressing or pressure ironing of shirts and other garments, and has for its principal object improvements in the means for adjusting the pressure of such presses.

Other objects and advantages of the invention will appear in the following description and accompanying drawing.

In the'drawing: j

Figure 1 is. a side viewof a typical laundry press equipped with my improved feature.

Figure 2 is an enlarged vertical section of the upper buck or pressure head as seen from th line 2-2 of Figure 1. v

Figure 3 is a further enlarged vertical section of the device as seen from the lines 33 of Figure 2.

Before describing the drawing in detail, it may be stated that laundry presses of the type to which my invention pertains are made for power and manual operation, and take the general form shown in Figure '1, wherein a heavy pedestal or frame I supports a lower buck. 2 over which the garment to be pressed is spread, and an upper buck or complementarily formed, steam or otherwise heated presser head 3 carried at the forward end of a pivotally mounted'pressure arm 4 is adapted to be brought down with considerable pressure against the work, either through power or manual force depending on the type of press. The present invention relates to the means for suspending the head 3 from arm 4 and adjusting the distance between it and the arm, so that any desired degree of as pressure may be obtained with a fixed travel of pressure arm 4 so that the stroke of the latter need never be altered. Y

The means employed in my construction is an improved form of wedge adjustment combined with spring suspension of the upper pressure head or buck. I

The pressure arm 4 is pivoted at 5 to the press frame and the arm is bifurcated forward of its pivotal point beginning at about 6 of Figure 1 so that above the'presser head 3 there are in fact two laterally spaced arms 6' and 6", or extensions of 6 as shown in Figure 2, andfrom each of which extensions the presser head 3 is suspended at two pointsby coiled compression springs I pocketed in recesses 8 formed in the extensions, and extending through which springs are bolts 9 threaded at their lower ends into a flat boss Ill formed on the presser head 3.

Bolts 9 are fitted with washers H under their '55 heads 9' resting on the upper ends of the springs,

ment therein. v

The tension of the springs is sufficient to overcome the weightof the presser head 3 and nor-' 5 mally keep it raised as far as permitted by two pairs of pressure adjusting wedges l3, l4.

These wedges are arranged horizontally between the presser head and arms 6', 6", with lower wedges l3 secured to bosses Hi as by cap 10 screws I4 recessed at the large ends of the wedges both of which large ends are outward of their respective arms,-f6 and 6", and the upper wedges Mare each provided at their large ends with an upwardly curved arm I5 having a hub threaded internally. and respectively engaged by the threaded ends of a horizontally arranged bar 11. I

The threading of hub I6 is respectively right and left hand, as is also the opposite ends of the 20 bar I! as at IT so that upon turning the bar both upper wedges will either be forced apart or drawn toward one another, depending on which way the bar is turned; thereby forcing the pressure head 3 downward when the wedges 5 are moved outwardly and compressingsprings 8, and vice versa. k

The threaded bar is relatively large in its centralportionand milled as at H" to-aflford a proper grip'for turning by hand, and the ends of 0 the bar are drilled out as at I8 and supported forrotation asby stub axles l9 projecting into the hollow ends of the bar from the inner sides of arms '6 and 6". Stub axles ii! are supported in horizontally drilled holes in arms 8 and 6" 35 and locked in position as by set screws 2b.

The wedges are of oblong cross section and formed with interlocking tongue and groove 2|, 22, extending longitudinally as shown in Figures 2 and 3 tohold thepresser head orv upper buck 40 laundry press having a bifurcated pressure arm,

it is manifest that it may be applied to double pressure arms or other forms of arms with suitable modification to carry out the objects and advantages of the invention as above set out.

I therefore claim:

1. In a laundry press having an upper presser buck carried by a presser arm, spring means suspending the buck below the arm and normally urging the buck upward, two pairs of oppositely directed wedges positioned between the arm and the buck, and means for variously,- adjusting said wedges for forcing, the buck, down" against the action of said spring means comprising a threaded hub on one of each pair of wedges threaded right and left respectively, a bar threaded right and" left at its opposite endsengaging in saidhubs,

means facilitating turning of. said bar, and means,

preventing longitudinal motion of saidlbar.

2. In a laundry press having an upper presser buck carried by a presser arm, spring means sus'-- pending the buck below the arm and normally urging the buck upward, two pairs of oppositely directed: wedges positioned-between the arm and the buck, and means for variously adjusting said wedges for forcing the buck down against the action of said spring means comprising a thread ed hub on one of each pair of wedges threaded right and left respectively, a bar threaded right and left at its opposite ends engaging in said hubs, means revolvably supporting said bar from said arm, means facilitating turning of said bar, and. means preventing longitudinal motion of said ba'r. I

3. In the construction specified'in claim 1, the wedges of each pair provided with tongue and grooved working faces.

4. Ina structure as specified in claim 2, said armhavingtwo spaced sections and the means revolvably supportingthe bar comprising a pair of stub axles projecting respectively from the presser arm sections: and into sockets formed in the ends of said bar,

STANLEY MARVIN.
